MILK-COOLER.

Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed July 5, 1906. Serial No. 324.874..

To all whom it may concern:

e it known that I, JOHN WEsLEY J ONES, a citizen of the United States,residing at Auburn, in the county of King and State of Washington, haveinvented certain new and useful Improvements in Milk-Coolers, of whichthe following is a specification, reference being had therein to theaccompanying drawings, in which- Figure 1. is a plan view of apparatusembodying my invention and shown partly broken away; Fig. 2 is a sideelevation of the same, similarly treated; and Fig. 3 is an enlargedfragmentary vertical section.

My invention relates to dairy apparatus.

It is a well known fact that milk at the temperature at which it is hadfrom the cows is susceptible, to a high degree, to becoming soured andespecially so when thus placed in shipping receptacles and subjected toagitation due to transporting to the consumer or creamery. Difficultyhas hitherto been experienced in the obtainment or a reliable device foreffecting the cooling of the milk and one which may be had by farmers,or the like, having but a few animals.

It is the object of this invention to furnish a milk cooler of verysimple and economic construction, which will be durable and efficient inoperation, and adapted to accomplish the elimination of theobjectionable animal heat from the milk with a relatively smallconsumption of water as the cooling medium.

The invention consists in the novel construction, adaptation andcombination of parts as will be hereinafter described and claimed.

The reference letter a, in the drawings,

designates a cooling pan having three rectangularly arranged edges andan oblique edge a and is provided thereabout with an upwardly" extendingwall I). In operation the pan is inclined, as represented in Fig. 2,with said oblique edge at the lower side whereby the milk is directed toa discharge spout 0 provided at the lowermost corner. The pan islikewise provided with a two-part bottom .01 and e which parts arespaced apart to provide an intervening compartment f through which thecooling water flows from the inlet nozzle g at one of the lower cornersto an outlet nozzle h at one of the upper corners and in its passagetherebetween is directed in a sinuous course by the provision oftransversely arranged partitions 7c. These partitions, as will beobserved in Fig. 1, do

i not extend entirely across the compartment and are disposed toalternately project from the opposite sides.

Detachably connected to the pan at its upper edge, as by an overlappingoffset strip m engaging with the pan'wall thereat, is the milk receivingtrough n which may advantageously be supported upon legs 0 disposed upontheopposite edge of the trough from the said strip. The trough isdesirably of box-shape in cross section and at its lowest transversecorner is provided with a plurality of perforations p. In practice themilk is supplied to the trough, thence dribbling through saidperforations it spreads in a thin film over the pan fioor d and thusflows toward the lower edge of the pan whereat it is led by the obliquewall to the said discharge spout to be delivered into a suitable vessel.Meanwhile the water enters the pan from the lower edge and flows, asindicated by arrows in Fig. 1, to the discharge nozzle and in so doingabsorbs the heat from the milk through the intervening bottom part d. Bysuch an arrangement, that is the introduction of the water along theline of the discharge of the milk, the cooling effect of the water ismore effective than would be the case than if the current was reversed,as the difierence in temperature between the water and the milkthroughout the area of the pan bottom varies correspondingly and thecooling of the milk is gradually attained in the most effective mannerand with a minimum of water. I have found that the water obtainable fromordinary wells sufiiciently cool to accomplish the purposes of theinvention and to be capable of rendering the milk acted upon in a fitcondition for shipping or storage. The apparatus requires littleattention and has proved to be valuable where used.

Having described my invention, what I claim is- A milk cooler comprisinga pan formed with four upwardly extending walls, two side walls and anend wall of said walls being disposed at right angles to one another,the other end wall of said walls being arranged obliquely to the firstend wall and being of greater length than the same and extending beyondone of the side walls to form one side of a spout, the bottom of saidspout being formed of a continuation of the top of said pan, the otherside of said spout being formed of a continuation of one of the saidside walls, a milk trough rectangular in cross section fitfeetdetermining the inclination of the bottom of said trough with respect tothe pan top.

In testimony whereof I affiX my signature in presence of two witnesses.

JOHN WESLEY JONES.
